Unable to run .NetCore 2.0 tests from command line using Nunit3-console.exe

I have a simple .Net Core 2.0 project containing only the following tests:

`using NUnit.Framework;

namespace TestStuffCore { [TestFixture] public class Class1 {

    [Test]
    public void TestStuff1()
    {
        Assert.AreEqual(1 + 1, 2, "Equal");
    }

    [Test]
    public void TestStuff2()
    {
        Assert.AreEqual(1 + 1, 3, "Not equal");
    }
}

} `

Nuget packages installed: Microsoft.NET.Test.Sdk v15.5.0 Microsoft.NETCore.App v2.0.0 NUnit v3.9.0 NUnit.Console v3.8.0 NUnit3TestAdapter v3.9.0

Running them from Visual Studio Test Explorer, everything works fine.

Running them from console line fails with the following error:

Further investigations: 1.) Running the exact same test code from a project targeting .Net Framework works as expected. 2.) Running the exact same test code from a project targeting .Net Core, but using NUnit.Console v3.7.0 results into the following error:

@spokcarls dotnet test is the way to go at the moment. As Rob says in https://github.com/nunit/nunit-console/issues/364#issuecomment-361706848 - we’re hoping to support .NET Core in the full engine/console at some point - as ever, that’s based on willing contributors!

We should definitely give more information from the runner itself.
